====== Accessories ======

To keep the launch price under £400, Sinclair left out many items that most owners would consider essential, such as indicators, mirrors and the High-Vis Mast, and sold them as accessories. The **C5 Accessories catalogue** (9 pp.) came in every owner's pack. Accessories were ordered direct from Sinclair Vehicles Ltd (FREEPOST, Camberley), by post or by phone with Access, Barclaycard or Trustcard. Each one carried a one-year guarantee and a 7-day money-back offer.

===== Fitting notes (from the original Sinclair fitting instructions) =====

==== Direction indicators ====
  * **Kit contents:** front repeater assemblies ×2, rear assemblies ×2, flasher, switch, 4-way and 3-way terminal blocks, 15 cable clips, 250 mm black/white wire, hole cutter, template, lockplates and spring clips.
  * **Wiring:** most of it is already in the C5. The connecting wires are stowed as a folded loop inside the black tubular trunking on the seat back, and the repeater wires connect to the existing 9-way bundle to the pod using the 3-way block.
    * Colours: Violet/White, Red/White, Blue/White, Black/White.
    * **Alternative harness:** if the wiring differs, look for a cluster of 6 connectors under the tunnel near the rear brake arm. In that case cut back the trunking about 40 mm and fit the 4-way block, cutting and joining the Blue/White, Red/White and Violet/White loops.
  * **Front repeaters:** use the template to drill three 2 mm holes, then open out the centre hole to 16 mm with the supplied cutter. Fit with the lens "weep" hole at the bottom.
  * **Switch:** mounts on a plate on the extreme right-hand edge of the seat, with two self-tapping screws in 2 mm pilot holes. Wires go through a 10 mm hole in the bulkhead.
  * **Rear indicators:** drill two 2 mm pilot holes per the template, open out to 10 mm, then fit with a foam gasket and spring clip.
  * **Bulbs:** front repeaters **12 V 5 W wedge**; rear **12 V 10 W festoon**.
  * **Cable clips:** these are self-adhesive. Clean the surface with warm water and detergent first, then press firmly for a few seconds.

==== Horn ====
  * **Kit contents:** horn with leads, 5 cable clips, brake clamp and switch with leads, bolt, nut and washer, 4-way terminal block, 250 mm black/white wire.
  * **Switch:** remove the steering-bar cover, peel back the right-hand grip, and replace the brake-lever bracket clamp with the new clamp and switch assembly. Plug its two wires into the empty connectors on top of the steering stem, matching colours.
  * **Horn:** bolt it to the rear wall of the **left** footwell through a 5.5 mm hole, using the template.

==== High-Vis Mast ====
  * **Kit contents:** 2 mounting poles, reflector moulding, red and white reflective decals, 2 small plugs, 2 large plugs, 2 drive rivets.
  * **Fitting:**
    - Apply the decals: red to the rear, white to the front.
    - Fit drive rivets into the pole ends.
    - Remove the plugs from the grommets on top of the seat back and push the poles in until they locate in the **cups under the top of the seat back**.
    - Smear petroleum jelly inside the top of the poles, push in the small ball plugs, and press the reflector moulding on.
    - Remove the rear lamp and press the large plugs into the cups at the top of the rear location frame.
  * **Removal:** take off the reflector moulding without distorting the lugs, then pull the poles up. You need to do this to fit the tonneau.
  * //Which?// reported all the masts on its test vehicles snapping. The **AA**, //Which?// and the Dutch authorities all said the mast should have been **standard equipment**.

==== Rear-view mirrors ====
  * **Kit contents:** mirror (L or R), spacer, fracture plate, 2 screws, 2 lockwashers, 2 washers, 2 square nuts.
  * **Fitting:** use the spacer as a template to drill two **3 mm** horizontal holes through the body flange. Fit the fracture plate and spacer, then the mirror case, with the square nuts captured inside the case flange. **Don't overtighten.**
  * The fracture plate is deliberately designed to break in an impact.

==== Spare (second) battery ====
  * **Fitting:** the retaining plate is fitted with plastic rivets into existing holes in the **right-hand footwell**. The two-part strap anchorages need 3 mm holes drilled using the template, with large reinforcing washers on the outside.
  * **Two ways to use it** (Sinclair "Using a Second Battery" sheet, part no. 100959/3/85):
    - **As a spare.** Swap it into the **left** footwell when the first battery is flat. **Never drive on the right-hand battery alone.** Only the left-hand battery is monitored by the protection circuit.
    - **In parallel**, using the second-battery connection kit and a second (right-hand) master security switch.
      * Both batteries must be at the **same state of charge**.
      * Switch the **left-hand switch to D first**, then the right. Otherwise the battery-sensing circuit won't work properly.
      * **Remove the right-hand key** before driving.
      * **Both** cut-out buttons must be pressed to isolate the motor.
  * **Safety:** with the left battery switched on, the terminals of a parked right-hand switch are **live**. Always secure it in its **park bracket**.
  * **Charging:** use one charger per battery. Don't charge both from one charger.
  * Range is up to about 40 miles with two batteries (Sinclair's claim). Wiring them in parallel gives more than using them one after the other; see [[guides:specifications|Specifications]].
